Which X-Pipe?
 

My 90Z has ported plenum & IJH, SW headers, hi flo cats, and Borla Challenge exhaust (2-3/4"). I'm interested in changing the resonator to x-pipe.

I've already searched this forum and the "other" forums but not quite sure I've gotten all the answers.

1) Anyone have this combo? (headers, Borla Challenge & x-pipe). If so, please list pros & cons of this setup (i.e. what you like/don't like).

2) Can anyone suggest a stainless x-pipe that won't break the bank and will fit the Borla setup with the least amount of fitment hassle? I'm thinking that a 3" x-pipe might work best in this setup provided it fits OK. btw, I think the Magnaflow 3" x-pipe, while it looks good, is too wide to easily fit.

Thanks,
George

Re: Which X-Pipe?
 

George, from my vague memory of the Borla set up, I believe it is a 2.75 diameter system, which will cause you some headaches in going with a 3" x-pipe. Most of the x-pipes on the market are designed to fit with the B&B system it seems, unless you are doing custom fab of your complete system.

How is installation of the pieces going? BTW, I'll be down at SGC in Nov.

Jeff,
The Borla is indeed a 2.75 setup. Since I have various pieces & parts of several systems, adapters, etc. available to measure & put together, I believe that 2.75" pipe which is "slightly" expanded will fit very nicely inside 3" pipe. The main fitment issue will be the center to center dimension. I can't at the moment easily access the underneath of my Z to measure the center to center dimension but I'm guessing that it is between 3.75" & 4.5" (i.e. approx. 1" to 2" space between the pipes). Do you happen to know the dimensions of the SW x-pipe (i.e. length, width, pipe size, center to center, etc.)? Also, can you PM me with a price on the SW?

Haven't started installation but plan to real soon. Just got back from the doctor a few minutes ago (follow up visit). Right lung has improved but still have crud showing up in the x-rays. Apparently I had a much more severe case of pneumonia than I even realized and the recupe time is going to be another 6-8 weeks or longer to get back totally 100%. But I'm feeling better and stronger each day, walking about a mile each day to build up stamina, and starting to get back on all my "undone" projects ... putting the Z back together is top priority since I'm planning on being at SGC with the Z. I'll definitely have to get you a "cold" one when we finally meet.

Any other help/info/advice on the x-pipe would be greatly appreciated. Thanks for your response.

See you next month.

George
